I'm thinking more like, when I run with a sweater and heavier sweatpants, but the time I'm at the 5km mark I'm seriously sweating. So, not just higher heart rate. I'm talking "feels like a fever" heat, for 20 minutes, a few times a week.
But I run with my heart rate low, I don't like exceeding 150 on these runs.
